T. all whom it may comer m Be it knownth'at I, ARTHUR EQDUNHAM,

a citizen of the United States, and a resi- This invent on relates to winding machines and more particularly to those in which the material is wound in the form ing description of a skein or hank. v. .The invention and its aims and obJects will be clearly understood from the followtaken in connection with the accompanying drawings 'of a machine embodying one formof the invention herein described for "illustrative purposes, the

invention in its true scope being more particularly pointed out in the appended claims.

" In the drawings: I p

.Fig. 2 is'a vertical elevation on l1ne 2-2 of Fig. 1, certain parts being shown in sec- Fig. 3 is atop plan view on line 3-3 of F ig. 4 is a detail, of the reel and its looking means together with the clamp. for the material to be wound and the winding arm; and I r 1 :Fig. 5 illustratesjthe.path followed by the winding eye, as viewed from abovein a vertical direction, I

In the illustrative embodiment .ofthe invention herein shown the reel comprises two hubs 2-2 mounted uponthe shaft. 4 and provided with-sleeves 6, 6 keyedto said shaft and j ournaled in bearings 7 These bearings are mounted onbrackets projecting forwardly from theside frame members 10, 10 to. which they are secured in any. suitable manner, asby bolts 12. The hubs 2,-2are each provided with a pluralityof arms 14 suitably secured in sockets 16 on the hubs. Herein each hub is provided with four arms 14 but any suitable number may be provided. The hubs 2,2 are adjusted angularly on the shaft 1 in suchl manner that each arm 14 of oneof the hubs is in alignment or in the same plane with an arm 14 of the other hub, the skein' or hank being herein formed or wound on those two arms of the twohubs that are in the same plane, and preferably about the two that are directed upwardly from the-hub, this being the operative position of the arms. By turning the shaft 4 the difi'erent pairs of arms on the two hubs may be brought into this operative position. Means are herein provided to hold or look the reel against rotation when any two'arms a're in operative position. This means may be of any suitable construction butherein it comprises a disk '18 secured to the sleeve 6 of one of the hubs 2, herein to the hub shown at the right in Fig. 1, see Figs. 1 aud t. In the periphery of the disk 18 there are provided four notches 20, each adapted to be engaged by a latch 22 when one of the arms 14; on each of the hubs 2 is in a vertical position,'this beingjthe operative position.

The latch is pivoted at 24. upon the bracket 8. An arm 26 projecting from the latch 22 at an angle from the latter has its free end pivoted toa rod 28 having its lower end pivoted to a treadle 30 mounted 'for rocking movement upon a shaft 32. This shaft is journaled at its opposite ends in the two side frame members 10. The spring 34 has one end connected at 36 to the vertical part of the bracket 8, its free end being connected ates to the free end of an arm 40 connected to the latch 22. The spring 34 tends to keep'the latch 22 in engagement with the notch 20 when the latter comes into proper position, and by pressing'downwardly upon the treadle 30 the rod 28 will be drawn downwardly to -swing the latch outwardly about its pivot 24 to free the reel so that the latter may be turned to bring another pair of arms 14c into operative posi with a horizontal slot 46 open at one end. The lower wall 48 of this slot is provided with an opening adapted to receive a pin 00 carried by an arm 52 projecting from'a sleeve 54 slidably mounted upon the rod 44 beneath the member 42. At its lower end the sleeve'54 is provided with an ear 56 which is located above and registers with an ear 58 projecting from the rod 44. Through the ears 56 and 58 there extends a rod 60 headed at 62 and encircled by a helical spring 64 bearing with its opposite ends against the ears 56 and 58 respectively. The lower end of the rod 60 is conveniently connected to the arm 26 of the latch operating mechanism above described.

From vthe above description itv will be readily understood that when the treadle is pressed upon to withdraw the latch 22 from the notch2 0 in the hub, the sleeve 54 will be drawndownwardly against the action of the spring 64, thus drawing the .pin 50 downwardly in the slot 46 of the member 42 and freeingthe material clampedbetween the upper. end of said pin and the upper wall of the member 42. If thet-readle be released the sleeve 54 will rise under the action of the spring 64 thus causing the in to clamp the material between it and the upper wall of'the member 42. H The upper end of said pin 50 will'preferably be relatively pointed more securely to hold the material.

The main shaft 66 of the machine. extends from front to rear thereof and is journaled in suitable bearings carried by the frame members and which it is unnecessary more fully to describe. The shaft 66 carries a' pulley 68 adapted to be driven by a belt from any suitable source of power. This pulley is loose upon the shaft 66 to -which it may be clutched when desired to drive the machine by any suitable clutch mechanism 70. Herein the clutch conveniently used is of the construction known asthe Johnson clutch which it sowell known that any fur ther description thereof is unnecessary. A

lug 72 is provided with studs74 engaging an annular slot 76 in the clutch sleeve 70, the other end of said lugbeing rigidly connected to a rod 78 mounted in fixed bearings 80, .80 and provided at its free end (not shown) with means for'operating 'the clutch in the usual manner. v 7

At its forward end the shaft 66' is provided with a bevelled gear 82 which is adapted to mesh with a bevelled gear 84 fast upon a vertical shaft 86. This shaft is journaled in a sleeve. 88 carried by a bracket 90bol ted or otherwise rigidly secured to the left side frame member 10, see Fig. 1.

The shaft 86 carries twocranks 92, 94 secured to the lowerandupper ends of said shaft respectively. I

The free end of the crank92 is connected by a universal joint 96 to one end of a link 98, the-other end of which is connected by a universal joint 100 to the endlo'f :an arm 102 rigidly secured to 'the'windingarm 104. The'lower end of the winding arm 104 is .pivotally connected by a universal :joint at which meshes with a worm 126 upon the rear end ofjthe main shaft :66, for the purpose'hereinafter more fully described.

' The free end of thecrank 94 is pivotally connected at '128'to a link 130, Figs. 2' and 3, having its other end pivotally connected at 182 to one end of a lever 1-34-pivoted at 136 to the frame of the machine; 'In'termediate its two ends, there is pivoted to thelever' 134 one end of a link-1'88 having its other end pivoted at 140 to a framell42 having a slot 144"" through whichcxtends the winding arm 104. %The "frame 142is pivoted substantially centrally I to a "cross member 146 of the frame ofthe'niachine.

From the above descriptionit will be ap' parent that by operation of-themainshaft 66,'the crank 92 will: impart to the winding arm 104 a swinging movement transversely of the machinewhile the-crank'94 acting through links 130 and '138-andlever" 134 and frame l42 will'inrpart to said winding arm a reciprocatingmovement from-front to rear ofthe machine. The resultant of these two movements will be to impartt-o the eye 148 'of the "winding lever a movement I v transversely of the machine substantially in the form of "an. elongated figure- 8, as

shown in"Fi'g. 5', and as'thei'upperend' of the winding arm 104' is curved rearwardly and then downwardly and forwardly, substantially as shown ,in'Fig; 4, so as to 'bring the eye 148 through which the material to be. wound extends, into the horizontal plane of theupwardly directed arms .14, 14 of the two reel members, the eye 148 in the motion described I will wind the material about said arms 14 in the' form ofa figure 8 or a'h'ank. Simultaneously 'with 1 the two *motions above described there willfbe imparted to j the winding arm 104 an up and down movement, by means of theworm 126, gea'r124',

crank'116,link,112, lever 109, shaft-32 and arm108, above described. This movement has for its object to preventthe windings fro-m piling u'puponeachrother upon'the arms 14, the reel, by; distributing them up and down the latter.

It Will be? understood-that during a e winding operation the freeend of the material to be wound is secured in the clamp 42,

' said material after passing through the eye Means, are provided to produce a slight drag on the materiahsaid means herein comprising a guide 158 having aneye 160 through which the material extends; Ihe guide is pivoted by a yoke l62'tothe PIVOE of the pulley 150 and thustendsto bind the material in. the groove of the pulley by the downwardly directed weight of said guide resting on the material. If desired said guide may be held downwardly by a spring. p

In operation, the material to be wound having been passed from the source of supply through the guide 158, over the pulley 150 and through theeye 14:8 of the winding arm, its free end is secured in the clamp 42 as above described and the clutch of the machine is then thrown in. The motions above described are thus communicated to the winding arm 10st which winds the material in the form of a hank upon the two then upwardly directed arms lt of the reel. \Vhen a hank of sulficient size has been formed the clutch is thrown out, the material is severed at a suitable distance from the hank and the fre end of the material having been released from the clamp 42 by downward pressure upon the treadle 30, the hank is removed from the arm 14:. To facilitate removal the arms 1-1 are mounted for rotary movement so that they may be turned inwardly, their inclined upper ends being turned outwardly during the winding operation in order the better to retain the hank upon the arms.

To hold the arms 14: in their inturned or out-turned position, said arms are provided with locking means, herein conveniently consisting of spring pressed latches 164 adapted to engagesuitably placed slots 166 provided in diametrically opposed position in a collar 168 upon said arm.

It will be apparent that it is not indispensable that all of the features of the invention be used conjointly, since they may be used to advantage separately in various combinations and sub-combinations. It will also be understood that, while the invention is herein described as embodied in the details illustrated, it 18 not to be considered I as circumscribed by or limited to these details. or any of. them, but that said details may be variously modified within the true scope of the invention which is definitely set forth by the claims. 1
